ncl_mapusr (3) - Linux Man Pages
ncl_mapusr: Called by EZMAP routines that draw the various parts of the map.
MAPUSR - Called by EZMAP routines that draw the various parts of the map. The default version does nothing. A user-written version may be supplied to change the appearance of the map. Note that this routine is not called by any of the EZMAPB routines; they call MPCHLN instead.
SYNOPSISCALL MAPUSR (IPRT)
(input expression, of type INTEGER), if positive, says that a
particular part of the map is about to be drawn, as follows:
- Part of map about to be drawn
- Limb lines.
- Continental outlines.
- U.S. state outlines.
- International outlines.
- If IPRT is negative, then the drawing of the last part is complete. The absolute value of IPRT will be one of the above values. Changed quantities should be restored.
USAGEEZMAP executes the statement
- CALL MAPUSR (IPRT)
just before and just after each portion of a map is drawn. The default version of MAPUSR does nothing.
EXAMPLESUse the ncargex command to see the following relevant example: mpex08.
ACCESSTo use MAPUSR, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
